    Abstract: Various embodiments of an airfoil and machines with airfoils are disclosed. The airfoils include a thicker leading airfoil portion and a thinner trailing airfoil portion. In one embodiment, the leading airfoil portion is formed by bending a body of the airfoil back toward itself. In another embodiment, the leading airfoil portion has a solid geometry and includes two elliptic surfaces. To prevent detachment of airflow, the leading airfoil portion includes at least two arc portions or surfaces that act to direct the airflow down to the trailing airfoil portion in a manner that stabilizes vortexes that may form in the region of changing thickness.

    Abstract: An air diffuser configured for use at the lower rear of an land vehicle may include an airfoil that, when located at the lower rear of a land vehicle, is oriented to redirect air passing under the vehicle upward behind the vehicle when the vehicle is traveling in a forward direction. The airfoil may have a leading edge, a trailing edge, an upper side, and a lower side, the airfoil cross-sectional shape including: a base portion including a first surface associated with the upper side and a second surface associated with the lower side; an overhang portion that extends under some of the base portion; and an elliptic portion connecting the base portion and the overhang portion adjacent the leading edge.

    IPC: B62D35/00

    Abstract: A land vehicle having an aerodynamic system includes a rear air diffuser positioned at the lower rear of the land vehicle and configured to redirect airflow from under the land vehicle upward behind the land vehicle while the land vehicle is traveling in a forward direction, and a rear wing positioned at the upper rear of the land vehicle and configured to generate downforce when the land vehicle is traveling in a forward direction. The rear air diffuser and the rear wing may be configured and arranged to merge the flow of air from underneath the land vehicle with the flow of air from above the land vehicle.

    Abstract: A turbine wheel may include an inner hub having a central axis, an outer ring concentric with the inner hub, and an intermediate ring concentrically disposed between the inner hub and the outer ring, and a plurality of turbine blades extending between the intermediate ring and the outer ring. The turbine blades may be oriented to be driven by a fluid stream flowing through the turbine wheel to rotate the turbine wheel in a first direction about the central axis. In addition, the turbine wheel may further include a plurality of compressor blades extending between the inner hub and the intermediate ring. Also, the compressor blades may be oriented to propel a fluid in a downstream direction when the turbine wheel is rotated in the first direction.

    Abstract: A golf club head for a driver is disclosed. The golf club head includes a face portion and a rearward end portion. An upward facing surface in a crown portion of the golf club head curves up towards the rearward end portion to keep airflow from separating from the crown portion. A downward facing surface on a sole portion of the golf club includes an airfoil that helps keep air stuck to the sole portion of the golf club head. The airfoil portion extends across a substantial entirety of the width of the golf club head.
